Abstract
The utility model provides a reusable split screw, which is characterized in that the reusable split screw comprises two solenoids and a supporting rod arranged between the two solenoids and connected therewith. A water stop is arranged on the supporting rod. The joint between the supporting rod and the solenoids is fixed with a locating pad. The tail end of the solenoids is provided with a wrench platform. Nuts are arranged on the solenoids. One end of the solenoids connected with the supporting rod is provided with a protective sleeve. The solenoids of the split screw are reusable and independent of the gas cutting, thus saving material, cost, time and labor. The supporting rod is solid without an internal leakage pipe, which has the advantages of good waterproof performance, large bearing capacity, safe and reliable assurance. Besides, the protective sleeve is arranged on the outer wall of the solenoids to avoid sticking and easily detach.
Description
Technical field the utility model relates to a kind of Screw arbor with nut at both-ends through walls, is specifically related to a kind of reusable Screw arbor with nut at both-ends.
Background technology need support and formboard fastening with Screw arbor with nut at both-ends through walls in the building wall in-situ casting and constructing.At present, in the exterior wall cast-in-situ concrete construction of building basement, the general whole screw rod through walls that has the sealing sheet that adopt.Adopt this whole screw rod through walls, after concrete pouring is finished, the screw rod that stretches out wall outer side must excise one by one with gas cutting, so not only waste time and energy, waste steel, and cause the template dismounting difficult, cause the breakage of template to scrap, increase construction cost, reduce speed of application and metope quality.In recent years, occurred a kind of can reusable Screw arbor with nut at both-ends, solved the waste problem of steel, template and manpower preferably.But, this can reusable Screw arbor with nut at both-ends, this can reusable Screw arbor with nut at both-ends, the part that is embedded in body of wall is a hollow section, though for anti-sealing seepage from hollow section, hydro-expansive rubber sealing piece is set in hollow section, and hollow section pushed, still can't guarantee the sealing of tube wall and sealing piece after the extruding fully, therefore, be embedded in the hollow section of body of wall and may form leakage passage.On the outer wall of hollow section, be with the hydro-expansive rubber seal ring, in the process of concreting, concrete may enter in the slit between hydro-expansive rubber seal ring and the outer tube wall, forming concrete directly contacts with outer tube wall, to produce the slit after the concrete setting, and make the seal ring on the hollow section outer wall completely lose the sealing function.And the life-span of hydro-expansive rubber is limited, after long-time the use, can wear out, damage or characteristic change, and might cause the sealing disabler.In addition, its detachable end is connected with the intermediate hollow tube portion by screw thread, and in the process of fluid concrete, concrete often drains to the junction of detachable end and intermediate hollow pipe by the slit between template and the supporting pad, after the concrete setting, cause screw rod dismounting difficulty.
The summary of the invention the purpose of this utility model is to provide a kind of economical with materials, percolation-proof, easily detachable reusable Screw arbor with nut at both-ends.
For achieving the above object, the technical scheme taked of the utility model is:
A kind of reusable Screw arbor with nut at both-ends, it comprises two screwed pipes and is arranged between two screwed pipes and the support bar that is connected with two screwed pipes, the sealing sheet is set, support bar and screwed pipe junction stationary positioned pad on the support bar, the screwed pipe tail end is provided with the spanner platform, and nut is set on the screwed pipe.
The end termination that described screwed pipe is connected with support bar is provided with protective sleeve.
A kind of reusable Screw arbor with nut at both-ends that the utility model provides, its screwed pipe is reusable, need not the gas cutting excision, and economical with materials reduces cost, and is time saving and energy saving; Support bar is solid, leakage passage in not having, and water resistance is good, and bearing capacity is big, and is safe and reliable.In addition, the screwed pipe outer wall is provided with protective sleeve, anti-adhesion, quick detachable.
Description of drawings Fig. 1 is a structural representation of the present utility model.
Among the figure: the 1-screwed pipe; The 2-support bar; 3-sealing sheet; The 4-locating pad; The 5-nut; The 6-protective sleeve; 7-spanner platform.
The specific embodiment as shown in Figure 1 be an embodiment of the present utility model, it comprises two screwed pipes 1 and is arranged between two screwed pipes 1 and the support bar 2 that is threaded with two screwed pipes 1 that screwed pipe 1 is a hollow tube, support bar 2 is a solid hopkinson bar.Sealing sheet 3 is set on the support bar 2, and sealing sheet 3 is for being welded on the support bar 2.Support bar 2 is provided with locating pad 4 with screwed pipe 1 junction, and wing nut 5 is set on the screwed pipe 1.The end termination that screwed pipe 1 is connected with support bar 2 is provided with protective sleeve 6; protective sleeve 6 is a plastic sheath; prevent in the process of fluid concrete; concrete drains to the junction of screwed pipe 1 and support bar 2 by the slit between template and the locating pad 4, causes screwed pipe 1 and support bar 2 inter-adhesive, not quick detachable.The tail end of screwed pipe 1 is provided with spanner platform 7, can unload screwed pipe 1 with spanner.
During use, the size of support bar 2 is set to the thickness of body of wall, and locating pad 4 is supported on the inboard of template, and the wing nut 5 that is positioned on the screwed pipe 1 is pressed in by chevron card, shelf pipe on the outside ancient piece of jade, round, flat and with a hole in its centre of template, realizes the stable support of template.After the concrete setting of cast, with spanner rotating spanner platform 7, can unload screwed pipe 1, in order to use next time, and support bar 2 and locating pad 4 are stayed in the concrete.
Above-described only is the utility model specific embodiment.Be noted that for a person skilled in the art, under technology enlightenment provided by the utility model, can also make other equivalent modifications and improvement, all should be considered as protection domain of the present utility model.
